Qumat®-Q401-HR
Protective gloves and other personal protective equipment are subject to continuous quality control. The quality of this equipment and its classification into different protection classes is regulated by standards. The relevant standards are DIN EN ISO 374, DIN EN ISO 16523, DIN EN ISO 6529 and F-739. The concentration of the chemical in relation to time are continuously recorded. As soon as the concentration exceeds a predefined value as a function of time, one speaks of a breakthrough. From this point on, the PPE no longer protects the user from the tested chemical. The breakthrough is defined according to the standard with a permeation rate > 1 µg min-1 cm-2.
Description
- Resistance to chemicals is regulated in standard DIN EN ISO 374, DIN EN ISO 16523, DIN EN ISO 6529 and F-739
- LABC-Permeation cells are manufactured according standard DIN EN ISO 374, DIN EN ISO 16523, DIN EN ISO 6529 and F-739
- For testing with 23°C+-1 according the standards. Tests up to 35°C are possible
- Economical use of permeation chemicals, as LABC-Permeation cells are used in an upright position. Approx. 10ml of liquid is required per permeation measurement
- Gaseous permeation chemicals can also be measured with a separate adapter
- Our permeation products are used worldwide
- LABC-Permeation cells and permeation testers are exclusively manufactured in Germany
- The permeation tests required for each permeation chemical are listed in the normative annexes
LABC-Labortechnik has developed various products for permeation measurement in laboratories since 1988. Our range includes products for measurements in the collection medium water as well as in the gas flow. As detectors we offer FPD, FID, PID electrodes, as well as pH electrodes, conductivity electrodes and redox electrodes.
Measuring devices in the gas flow
Our Qumat and Permobil workstation measure in the gas flow with a detector. This means that the collection medium is a gas. Here you have the option of using air or nitrogen as the collection medium. The measurements in the gas flow are carried out in an open loop system.
Workplaces with water as a collection medium
The NW50liquid workstation and the NW50 liqui permeation cells are operated with water as the collection medium. The collection medium is a deionised water. The permeation measurements take place in a closed loop system.
Qumat®-Q401-H
The Qumat®-Q401-HR analyser is used to measure the permeation rate of chemical protective gloves and clothing. The analyser measures the breakthrough of test chemicals in three permeation measuring cells according to DIN EN 374, DIN EN 6529, EN 16523 or F-739. The glove tester Qumat®-Q401-HR is available in two versions and differentiates only by its detector. The Qumat®-Q401-HR can be supplied with FID or with FID and FPD. The overview of detectable chemicals provides information on which detector is suitable for your application.
Gloves are clamped into the permeation measuring cells, filled on one side with the liquid test substance to be examined and continuously flown through from the other side with a gaseous collection medium. These three defined gas streams are analysed in sequence for the volatile detectable test substance. The results are documented in tabular form. In addition, the temperature and airflow are recorded for each measurement.
If a test substance with a permeation rate > of 1 µg min-1 cm-2 passes through the test specimen, a breakthrough according to DIN EN 374-3 and EN 16523-1 is present.

Permeation cell NW50
Designed for liquid or gaseous test chemicals and gaseous collection media. Permeation cell NW50 according to EN 16523-1 (replaces EN374-3) for testing PPE films such as protective gloves or protective clothing to measure the permeability of the test substances for the samples.
The permeation cell parts are held upright by a tripod without support. The PTFE holder for gloves < 0.5 mm is placed in between. Made by German glassblowers according to the standards.
